Additional Info

• This code the following types of intra-peritoneal infections:
  • Generalized ("regular") acute peritonitis
  • Spontaneous Bacterial Peritonitis (SBP) -- this is an entity that occurs in people with pre-existing ascites
  • Abscesses that aren't included in the Alternative codes listed below, thus included in this code are:
    • "intra-abdominal abscess" (intraabdominal abscess) or "abdominal abscess" or "intra-pelvic abscess" (intrapelvic abscess) or pelvic abscess that don't have any additional information about where it originated (e.g. as below, abscesses related to diverticulitis or appendicitis, and a few others, have their own specific codes)

• This code EXCLUDES the specific causes/types of abdominal or pelvic infections as listed below
• Often abdominal paracentesis is done to test the fluid for WBC and cultures
• A diagnosis of SBP is usually made by finding polymorphonuclear cell (PMN, also referred to as neutrophils) count in the ascitic fluid is ≥250 (or 500) cells/mm3, and secondary causes of peritonitis are excluded
  • Culture results might be negative if antibiotics were started before the sample was taken; you can still code this with a pathogen of Infectious organism, unknown
• Peritonitis

Alternate ICD10s to consider coding instead or in addition

• Disorder of peritoneum, NOS

Candidate Combined ICD10 codes

Infections

Infections in ICD10 have combined coding requirements for some of their pathogens. Any that have antibiotic resistances would store those as Combined ICD10 codes as well. If the infection is acquired in the hospital, see Nosocomial infection, NOS. See Lab and culture reports for confirmation and details about tests. See Infections in ICD10 for more general info.
